CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE CAR CONSTRUCTIONApplication filed July 27,

This invention relates to improvements in car construction.

@ne object of the invention is vto provide ay simple and efficientlocking center pin arrangement for body and truck holsters of railwaycars, wherein the pin isl composed of a plurality of headed sections,the heads of each section having shouldered engagement with therespective holsters to prevent reio Inoval of the pin, and the body andtruck holsters are provided with aligned pin receiving openings soformed that the headed sections of the pin may he assembled insuccession with the holsters and then turned to i5 engaging relationwith the shoulders of the holsters, and wherein the pin is locked to oneof said holsters against relative rotation to prevent disengagement fromsaid holsters.

Another object of the invention is to pro- 2o vide a combined lockingand center pin arrangement for body and truck 'holsters of railway carsprovided with aligned shouldered center pin receiving openings, whereinthe center pin is composed of a plurality of headed sections and theshoulders of the bolster center pin openings are cut away to permitinsertion of the headed sections, one at a time, said sections beingassembled with the holsters in succession and rotated'to posi- 3o tionthe heads of the same in engagement with the shoulders of the holstersto prevent removal of the pin sections, andwherein a filler member isalso provided for said cut-away portions of the shoulders, said fillermember being interposed between the heads at the opposite ends of saidsectional pin and filling the space therebetween. f

Other and further objects of the invention will more clearly appear fromthe description and claims hereinafter following.

In the drawing, forming -a part of this specification, Figure l is a topplan view of the central portion of a body bolster of a passenger car,illustrating my Vimprovements in connection therewith. Figure2 is avertical sectional view through the body and truck holsters of said car,at the central portion thereof, corresponding substantially to the line22 of Figure l. Figure 3 is a horizont-al, transverse sectional view,correspond- 1928. Serial No. 295,654.

ingsubstantially to the line 3 3 of Figure 2. And Figure 4 is a bottomplan view of the central portion of the truck bolster shown in Figure 2.

In said drawing7 10 indicates generally the 55 body bolster of therailway car and 11 the truck holster thereof. The body holster 10 isprovided with a hollow, cylindrical, sleevelike section V12, adapted toaccommodate the locking center pin. The truck bolster 11 is ee alsoprovided with a similar hollow, cylindrical, sleeve-like section 13,which receives the center pin. The body holster is provided with theusual downwardly projecting spherical bearing member 111, which isseated e5 within a hearing pocket- 15 provided in a bearing block 16supported on the top of the truck bolster. In carrying out my invention,I provide a sectional center pin A, headed at opposite ends, and so formthe open- 7o ings of the pin receiving sleeve sections of the body andtruck holsters as to permit assembling of the sections of the pin, oneat a time, with the holsters.

The body bolster 10 is provided witha hori '75 Zontally disposed,interior rib 17 on the n sleeve-like section 12 thereof, the rib 17being cut away, as indicated at 19, for a purpose hereinafter described.Adjacent the bottom end of the sleeve 12 of the body holster, a gosimilar rib is provided which is also indicated by y17, the same beingalso out away, as indicated at 19, and the cut-away portion thereofhein@ in alignment with the cutaway portion of the rib at the top of thesleeve 12. The truck holster is provided with van interior rib 18 onthesleeve 13 thereof, which is spaced from the bottom end of saidsleeve, as clearly shown in Figure 2, and is cut away corresponding tothe rib 17 the cut-away por- 9o tion being also designated by 19, for apurpose hereinafter pointed out. At the top,

the sleeve-like section is also provided with an interior rib similar tothe rib 18, which is also designated by 18. The rib 18 has a 95 sectionthereof correspondingly cut away to the bottom rib 18, said cut-awaysection being also designated by 19. The solid portions of the ribs17-17 of the body holster sleeve section 12 andthe solid portions of the10o ribs 18-18 of the truck holster sleeve 13 are of the same length,and the cut-away sections of the ribs are so located that the same willbe in substantial alignment when the holsters are disposed in parallelrelation. rl`he sections of the openings of the sleeves of the body andtrucl; holsters ahoi'e the top rib 17 of the body bolster and below thebottom rib 18 of the truck holster provide pockets adaptedl'toaccommodate the heads at the opposite ends of the sectional pin A.

The sectional pin A is preferably composed of four sections Ztl-20,which are of sectorshaped horizontal cross section. .fteach end, eachsection 2O is provided with a head portion 21. As shown, when the ofthepin are assembled, the same form the complete cylindrical pin, memberhaving a shank of true cylindrical cross section and havingeultrgclheads at opposite ei thereof, which are also of true circularcross sect-ion. As shown, the head portions 21 of the sections 2O .ofthe pin are of such a size that when the pin is assembled theycompletely lill the head receiving pockets of the holsters. The cutnaway portions ,of the ribs 17 and V18 `of such asize as to freelyaccommodfate the head por-tion of eachpin section 20, so that theVsections may he inserted Within the pin receiving openings oftheholsters in anendwise direction. Y v

ln assembling the sections of the pin A. with the holsters, it will heevils ent that the Afirst section may he passed freely through 'thecentral portions of the openings of the bolsters yand may then he movedto one sine to engage the head sections 21 thereof, over the rihs 17 and18 `of the holsters. rlhe said tion may also be placed in position byregistering the head portions 21 thereof Witl the openings between thesolid portions of vthe rihs 17 and 18 of the body and truck holstersand-then passing the section Within .the openingsof the holsters Whileguiding the head portions 21 through said cut-auf'ay sections of theribs. The pin section is then rotated in position to overlap the headsections thereofV with the ribs 17and 18, and so as to clear the4cut-away sections vbetween :the solid' portions of ysaid ribs.

The next section may then be inserted either through the-topof thebodybolster or through tfhehottom of the `truck bolster, with the headsectionsV thereof so .positioned `as to thro-ugh the cutsaway portionsof .the rizhs 17 and 18. `Wthen .this section has been brought intoregistration with the first section, the same is ,turnedto one side so.as to en "e head portions I21 thereof .with the ribs 1? and lsst ftheouter ends of the vopenings ofthe 'body and ,truck holsters.hlie'remaining ytivo sections areinserted in similar manner andaifterlthe last section has abeeninserted the entire pin is'hodilyrotated so as to bring 'both ,theseetion first: assembled and.theseotionzlast assembled in overlapping relation to the openingbetween the solid sections of the rihs of the holsters. he pin is thenlocked in position to either of the holsters by any Well known means. lnthe present instance, the pin is shown as locked to the body bolster, aCotter pin 22 being preferably employed AWhich extends through alignedopenings in all of the sections of the pin and aligned Vopeningsinidiametrically opposite portions of the side Wall of the sleeve 13 ofthe body bolster. As Will be evident, the sections of the pin are thusheld against relative rotation with respect to the body holster andcannot therefore become disengaged rom said holster@ It is furtherpointed out that Iordinarily in the operation of railway cars on curvedtrack, the angular displacement fof the holsters with respect to ,eachother will snflicient to disengage the tW-oY .adjacent sections whichoverlap the openings het-Ween the solid portion Lof `the ribs, from saidribs; hut even in case this does occur, the Cotter pin Will preventremoval of the section of the pin A, which might otherwise he displaced.

ln xorder to close the cut-away sections of the ribs, l provide La`iiller plate 23, which is showyL in dotted lines in Figure 2 andillustra-ted in full lines in Figure 3. This -filler plate is of curvedcross section and fits between the outer walls of the openings in thesleeves 12 `and 13 Yand theshanlrofthe pin A. The filler plate is ofsuch a Width as to sub.- stantially fill the 4openings between ytgl-.ieportions of the ribs 17 and 18,.and is rof such a height as to lill ithespace betiveenggt-lre heads at the opposite ,Y as of the,comhinedloclring and center pin il. TWhen the filler plate is employed,the same is assembled with the bolsters andthe locking pin A during theplacin posivtion'vof the last section of the pin, the filler slate beinglirst positioned between the headportions 21 at 4the ,opposite ends ,ofsection toff :the pin ,and then inserted the pin receiving openings .ofthe holsters with said section of the pin.

From thel preceding description, taken in connection With -thedrawings,it will he evident that l have provided a sectional pin ofexceptionally rugged ldesign and Agreat strength, which has relativelylarge shoulders in hearing engagement with the tivo :holsters of the carunderframe structure lto ,effectively anchor said holsters to eachother.
